Let's say I am declaring an obj in test1.js.

const NodeCache = require( "node-cache" );
const myCache = new NodeCache( { stdTTL: 100, checkperiod: 120 } );

obj = { my: "Special", variable: 42 };
 
success = myCache.set( "myKey", obj, 10000 );

Is it possible to access "myKey" in test2.js during running?

If yes, how can I do it?

If not, how to access "myKey" in some child nested functions? Through multiple passing as the parameter?
